| 1 | 血管性认知障碍的诊断标准:国际血管性行为与认知障碍学会的申明显示文摘长期以来,脑血管病(CVD)就被认为是认知损害的一个重要原因,但是有关脑血管病后认知障碍的概念化却有着一段多变的历史。'动脉变硬'或脑的动脉粥样硬化是'老化'的原因,是存在已久的观点,在20世纪60年代受到了来自英格兰纽卡斯尔的神经病理学研究的质疑。这些研究表明,血管性痴呆(vascular dementia,Va D)与超过一定程度的多发性脑梗死有关。 | 徐岩 郭起浩 Sachdev P Kalaria R O'Brien J Skoog I Alladi S Black SE Blacker D Blazer DG Chen C Chui H Ganguli M Jellinger K Jeste DV Pasquier F Paulsen J Prins N Rockwood K Roman G Scheltens P | 2014 | 神经病学与神经康复学杂志2014，11，3： | 19 |
| 2 | High-flow nasal oxygen availability for sedation decreases the use of general anesthesia during endoscopic retrograde cholangiopancreatography and endoscopic ultrasound显示文摘AIM To examine whether high-flow nasal oxygen(HFNO) availability influences the use of general anesthesia(GA) in patients undergoing endoscopic retrograde cholangiopancreatography(ERCP) and endoscopic ultrasound(EUS) and associated outcomes.METHODS In this retrospective study, patients were stratified into 3 eras between October 1, 2013 and June 30, 2014 based on HFNO availability for deep sedation at the time of their endoscopy. During the first and last 3-mo eras(era 1 and 3), no HFNO was available, whereas it was an option during the second 3-mo era(era 2). The primary outcome was the percent utilization of GA vs deep sedation in each period. Secondary outcomes included oxygen saturation nadir during sedation between periods, as well as procedure duration, and anesthesia-only time between periods and for GA vs sedation cases respectively.RESULTS During the study period 238 ERCP or EUS cases were identified for analysis. Statistical testing was employed and a P < 0.050 was significant unless the Bonferroni correction for multiple comparisons was used. General anesthesia use was significantly lower in era 2 compared to era 1 with the same trend between era 2 and 3(P = 0.012 and 0.045 respectively). The oxygen saturation nadir during sedation was significantly higher in era 2 compared to era 3(P < 0.001) but not between eras 1 and 2(P = 0.028) or 1 and 3(P = 0.069). The procedure time within each era was significantly longer under GA compared to deep sedation(P ≤ 0.007) as was the anesthesia-only time(P ≤ 0.001).CONCLUSION High-flow nasal oxygen availability was associated with decreased GA utilization and improved oxygenation for ERCP and EUS during sedation. | Roman Schumann Nikola S Natov Klifford A Rocuts-Martinez Matthew D Finkelman Tom V Phan Sanjay R Hegde Robert M Knapp | 2016 | World Journal of Gastroenterology2016，22，47： | 9 |
| 3 | Liver blood supply after a modified Appleby procedure in classical and aberrant arterial anatomy显示文摘Reported here are two cases of a modified Appleby operation for borderline resectable ductal adenocarcinoma of the pancreatic body, in one of which a R0 distal resection was attended to by excision, not only of the celiac axis, but also of the common and left hepatic arteries in the presence of arterial anatomic variation Michels, type Ⅷb. The possibility and avenues of the maintenance of the blood supply to the left hepatic lobe after surgical aggression of this kind are demonstrated employing computed tomography (CT) and 3-D CT angiography. Furthermore, both cases highlight all important worrisome aspects of pancreatic cancer resectability prediction. | Vyacheslav I Egorov Roman V Petrov Michail V Lozhkin Olga A Maynovskaya Natalia S Starostina Natalia R Chernaya Ekaterina M Filippova | 2013 | World Journal of Gastrointestinal Surgery2013，5，3： | 7 |

| 5 | 输尿管及膀胱深部浸润型子宫内膜异位症的手术治疗效果显示文摘目的报告泌尿道子宫内膜异位症的手术治疗效果以及探讨保守型手术和根治性手术的选择。方法对5个手术科室参与的输尿管或膀胱深部浸润型子宫内膜异位症外科治疗的CIRENDO前瞻性数据库管理数据进行回顾性研究。对术前、术中和术后数据结果进行分析。结果数据库中的数据显示,30例中有15例为输尿管子宫内膜异位症,14例为膀胱结节病变(bladder nodules),1例同时存在这2种类型的病变。输尿管松解术14例,其中输尿管完全恢复解剖解构10例。4例40岁以上的患者术后出现闭经和可忍受的中度输尿管狭窄,其中3例好转,1例行二次输尿管切除和输尿管膀胱吻合术。4例初次手术行输尿管切除术。5例输尿管标本中发现2例输尿管子宫内膜异位症。4例并发症中有2例与输尿管结节病灶切除有关,2例与膀胱子宫内膜异位病灶切除有关。远期效果较为满意,如疼痛症状显著改善、泌尿系不适症状消失,仅有1例较长时间膀胱神经功能障碍。结论建议保守性手术联合术后假绝经疗法治疗大多数泌尿道子宫内膜异位症。尽管总体结果满意,由于术中可能同时施行其他一些复杂手术如结直肠手术,术后并发症的风险仍不容忽视。 | 陈旭 刘彦 Francisc Rozsnyai Horace Roman Benoit Resch Fabrice Dugardin Juan Berrocal Gérme Descargues Remi Schmied Malik Boukerrou Loc Marpeau CIRENDO Study Group | 2013 | 中国微创外科杂志2013，13，2： | 3 |

| 7 | Hepatitis C virus genotypes distribution and transmission risk factors in Luxembourg from 1991 to 2006显示文摘AIM:To analyze the Hepatitis C virus (HCV) genotype distribution and transmission risk factors in a population of unselected patients in Luxembourg. METHODS:Epidemiological information (gender, age and transmission risks) were collected from 802 patients newly diagnosed for hepatitis C and living in Luxembourg, among whom 228 patients referred from prison. Genotyping using 5'noncoding (5'NC) sequencing was performed. We compared categorical data using the Fisher's exact F-test and odds ratios (OR) were calculated for evaluating association of HCV genotype and risk factors. RESULTS:The sex ratio was predominantly male (2.2) and individuals aged less than 40 years represented 49.6% of the population. Genotype 1 was predominant (53.4%) followed by genotype 3 (33%). Among risk factors, intravenous drug usage (IVDU) was the most frequently reported (71.4%) followed by medical-related transmission (17.6%) including haemophilia, transfusion recipients and other nosocomial reasons. Genotype 3 was significantly associated to IVDU (OR = 4.84, P < 0.0001) whereas genotype 1 was significantly associated with a medical procedure (OR = 2.42, P < 0.001). The HCV genotype distribution from inmate patients differed significantly from the rest of the population (Chi-square test with four degrees of freedom, P < 0.0001) with a higher frequency of genotype 3 (46.5% vs 27.5%) and a lower frequency of genotype 1 and 4 (44.7% vs 56.8% and 5.3% vs 9.6%, respectively). IVDU was nearly exclusively reported as a risk factor in prison. CONCLUSION:We report the first description of the HCV genotype distribution in Luxembourg. The repartition is similar to other European countries, with one of the highest European prevalence rates of genotype 3 (33%). Since serology screening became available in 1991, IVDU remains the most common way of HCV transmission in Luxembourg. | Francois Roman Karin Hawotte Daniel Struck Anne-Marie Ternes Jean-Yves Servais Vic Arendt Patrick Hoffman Robert Hemmer Thérèse Staub Carole Seguin-Devaux Jean-Claude Schmit | 2008 | World Journal of Gastroenterology2008，14，8： | 3 |

| 9 | Prediction of Dynamic and Aerodynamic Characteristics of the Centrifugal Fan with Forward Curved Blades显示文摘The main aim of this paper is determine the centrifugal fan with forward curved blades aerodynamic characteristics based on numerical modeling. Three variants of geometry were investigated. The first, basic 'A' variant contains 12 blades. The geometry of second 'B' variant contains 12 blades and 12 semi-blades with optimal length[1]. The third, control variant 'C' contains 24 blades without semi-blades. Numerical calculations were performed by CFD Ansys. Another aim of this paper is to compare results of the numerical simulation with results of approximate numerical procedure. Applied approximate numerical procedure [2] is designated to determine characteristics of the turbulent flow in the bladed space of a centrifugal-flow fan impeller. This numerical method is an extension of the hydro-dynamical cascade theory for incompressible and inviscid fluid flow. Paper also partially compares results from the numerical simulation and results from the experimental investigation. Acoustic phenomena observed during experiment, during numerical simulation manifested as deterioration of the calculation stability, residuals oscillation and thus also as a flow field oscillation. Pressure pulsations are evaluated by using frequency analysis for each variant and working condition. | Jií Polansky László Kalmár Roman Gápár | 2013 | Journal of Thermal Science2013，22，6： | 2 |
